US patent number 6,368,227

Here is a dumb patent in my series of dumb patents. US patent number 6,368,227. The introduction to the patent is:
"A method of swing on a swing is disclosed, in which a user positioned on a standard swing suspended by two chains from a substantially horizontal tree branch induces side to side motion by pulling alternately on one chain and then the other."
So, swinging from side to side on a swing is patented. Here is an actual quote from the patent text:
"The user may even choose to produce a Tarzan-type yell while swinging in the manner described, which more accurately replicates swinging on vines in a dense jungle forest. Actual jungle forestry is not required."

I don't think I even need to comment
